Pyrimidine type mevalonolactones
The present invention relates to novel mevalonolactones having a pyrimidine ring, processes for their production, pharmaceutical compositions containing them and their pharmaceutical uses particularly as anti-hyperlipidemic, hypolipoproteinemic and anti-atherosclerotic agents, and intermediates useful for their production and processes for the production of such intermediates. 
     Some fermentation metabolic products such as compactine, CS-514, Mevinolin or semi-synthetic derivatives or fully synthetic derivatives thereof are known to be inhibitors against HMG-CoA reductase which is a rate limiting enzyme for cholesterol biosynthesis. (A. Endo J. Med Chem., 28(4) 401 (1985)) 
     CS-514 and Mevinolin have been clinically proved to be potentially useful anti-hyperlipoproteinemic agents, and they are considered to be effective for curing or preventing diseases of coronary artery sclerosis or atherosclerosis. (IXth Int. Symp. Drugs Affect. Lipid Metab., 1986, p30, p31, p66) 
     However, with respect to fully synthetic derivatives, particularly hetero aromatic derivatives of inhibitors against HMG-CoA reductase, limited information is disclosed in the following literatures:

     The present inventors have found that mevalonolactone derivatives having a pyrimidine ring, the corresponding dihydroxy carboxylic acids and salts and esters thereof have high inhibitory activities against cholesterol biosynthesis wherein HMG-CoA reductase acts as a rate limiting enzyme. The present invention has been accomplished on the basis of this discovery.

     PHARMACOLOGICAL TEST EXAMPLES 
     Test A: Inhibition of cholestoerol biosynthesis from acetate in vitro 
     Enzyme solution was prepared from liver of male Wistar rat billialy connulated and discharged bile for over 24 hours. Liver was cut out at mid-dark and microsome and supernatant fraction which was precipitable with 40-80% of saturation of ammonium sulfate (sup fraction) were prepared from liver homogenate according to the modified merhod of Knauss et. al.; Kuroda, M., et. al., Biochim. Biophys. Acta, 489, 119 (1977). For assay of cholesterol biosynthesis, microsome (0.1 mg protein) and sup fraction (1.0 mg protein) were incubated for 2 hours at 37° C. in 200 μl of the reaction mixture containing ATP; 1 mM, Glutathione; 6 mM, Glucose-1-phosphate; 10 mM, NAD; 0.25 mM, NADP; 0.25 mM, CoA; 0.04 mM and 0.2 mM [2- 14  C]sodium acetate (0.2 μCi) with 4 μl of test compound solution dissolved in water or dimethyl sulfoxide. To stop reaction and saponify, 1 ml of 15% EtOH-KOH was added to the reactions and heated at 75° C. for 1 hour. Nonsaponifiable lipids were extracted with petroleum ether and incorporated  14  C radioactivity was counted. Inhibitory activity of compounds was indicated with IC50. 
     Test B: Inhibition of cholesterol biosynthesis in culture cells 
     Hep G2 cells at over 5th passage were seeded to 12 well plates and incubated with Dulbecco&#39;s modified Eagle (DME) medium containing 10% of fetal bovine serum (FBS) at 37° C., 5% CO 2  until cells were confluent for about 7 days. Cells were exposed to the DME medium containing 5% of lipoprotein deficient serum (LpDS) prepared by ultracentrifugation method for over 24 hours. Medium was changed to 0.5 ml of fresh 5% LpDS containing DME before assay and 10 μl of test compound solution dissolved in water or DMSO were added. 0.2 μCi of [2- 14  C]sodium acetate (20 μl ) was added at 0 hr(B-1) or 4 hrs(B-2) after addition of compounds. After 4 hrs further incubation with [2- 14  C]sodium acetate, medium was removed and cells were washed with phosphate buffered saline(PBS) chilled at 4° C. Cells were scraped with rubber policeman and collected to tubes with PBS and digested with 0.2 ml of 0.5 N KOH at 37° C. Aliquot of digestion was used for protein analysis and remaining was saponified with 1 ml of 15% EtOH-KOH at 75° C. for 1 hour. Nonsaponifiable lipids were extracted with petroleum ether and  14  C radioactivity was counted. Counts were revised by cell protein and indicated with DPM/mg protein. Inhibitory activity of compounds was indicated with IC50. 
     Test C: Inhibition of cholesterol biosynthesis in vivo 
     Male Sprague-Dawley rats weighing about 150 g were fed normal Purina chow diet and water ad libitum, and exposed to 12 hours light/12 hours dark lighting pattern (2:00 PM-2:00 AM dark) prior to use for in vivo inhibition test of cholesterol biosynthesis. Animals were separated groups consisting of five rats as to be average mean body weight in each groups. Test compounds at dosage of 0.02-0.2 mg/kg body weight (0.4 ml/100 g body weight) were dissolved in water or suspended or in 0.5% methyl cellulose and orally administered at 2-3 hours before mid-dark (8:00 PM), while cholesterol biosynthesis reaches to maximum in rats. As control, rats were orally administered only water or vehicle. At 90 minutes after sample administration, rats were injected intraperitoneally with 10 μCi of [2- 14  C]sodium acetate at volume of 0.2 ml per one. 2 Hours later, blood samples were obtained and serum were separated immediately. Total lipids were extracted according to the method of Folch et al. and saponified with EtOH-KOH. Nonsaponifiable lipids were extracted with petroleum ether and radio activity incorporated into nonsaponifiable lipids was counted. 
     Inhibitory activity was indicated as percent decrease of counts in testing groups (DPM/2 ml serum/2 hours) from that in control group. 
     With respect to the compounds of the present invention, the inhibitory activities against the cholesterol biosynthesis in which HMG-CoA reductase serves as a rate limiting enzyme, were measured by the above Test A and B. The results are shown in Tables 2, 2-2 and 3. Further, the results of the measurements by Test C are also presented.

     EXAMPLE 1 
     Ethyl (E)-3,5-dihydroxy-7-[4&#39;-(4&#39;&#39;-fluorophenyl)-6&#39;-methyl-2&#39;-phenylpyrimidin-5 &#39;-yl]hept-6-enoate (compound I-1-1) 
     This compound was prepared by the synthesis comprising the following reaction steps a o  to g. 
     a o ) Ethyl 4-(4&#39;-fluorophenyl)-6-methyl-2-phenyl-pyrimidin-5-yl-carboxylate (VIII-1) 
     This comound was prepared from p-fluorobenzaldehyde as the starting material via ethyl 2-(4&#39;-fluorobenzylidene)-acetoacetate and ethyl 6-(4&#39;-fluorophenyl)-4-methyl-2-phenyl-1,6-dihydro-5-pyrimidine-carboxylate in accordance with the process disclosed in Japanese Unexamined Patent Publication No. 40272/1986. 
     a o  1) Ethyl 2-(4&#39;-fluorobenzylidene)-acetoacetate (X-1) 
     8.69 g (7×10 -2  mol) of p-fluorobenzaldehyde, 9.11 g (7×10 -2  mol) of ethyl acetoacetate, 0.24 g (2.8×10 -3  mol) of piperidine and 0.84 g (1.4×10 -2  mol) of glacial acetic acid were dissolved in 40 ml of dry benzene dehydrated by molecular sieve, and the mixture was refluxed under heating at 100° C. for about 3 hours for azeotropically removing water. After confirming the disappearance of the starting materials by thin layer chromatography, the reaction solution was cooled to room temperature, and 50 ml of ethyl ether was added thereto. The mixture was washed three times with 100 ml of water and twice with 100 ml of a saturated sodium chloride aqueous solution. The ether solution was dried over anhydrous magnesium sulfate, and then the solvent was distilled off under reduced pressure by an evaporator. The residual oil was left to stand overnight in a refrigerator. The solid thereby obtained was recrystallized from hexane to obtain 14.08 g (yield: 85.2%) of slightly yellow prism crystals. Melting point: 80°-82° C. 
     a o  2) Ethyl 6-(4&#39;-fluorophenyl)-4-methyl-2-phenyl-1,6-dihydro-5-pyrimidine-carboxylate (XI-1) 
     8.42 g (3.57×10 -2  mol) of compound X-1 and 6.71 g (4.28×10 mol) of hydrochloric acid benzamidine were dissolved in 100 ml of n-butanol. Then, 9.74 g (9.64×10 -2  mol) of triethylamine was added thereto, and the mixture was stirred at 120° C. for about 1.5 hours. After confirming the disappearance of the starting material X-1 by thin layer chromatography, the reaction solution was cooled to room temperature. Then, 100 ml of ethyl acetate was added, and the mixture was washed three times with 100 ml of water. Then, 3% dilute hydrochloric acid was added until the aqueous layer became pH 2, followed by washing and liquid separation. The organic layer was washed with 100 ml of water, and then a saturated sodium bicarbonate aqueous solution was added until the aqueous phase became pH 8, followed by washing and liquid separation.

     6.65 g (18.4 mmol) of cis-1-ethoxy-2-(tri-n-butylstannyl)ethylene was dissolved in 180 ml of dry tetrahydrofuran, and the solution was cooled to -78° C. under a nitrogen stream. To this solution, 13.2 ml (20 mmol) of a 15 wt % n-butyllithium-n-hexane solution was dropwise added, and the mixture was stirred for 45 minutes. Then, a solution obtained by dissolving 3.08 g (9.2 mmol) of compound VI-10 in 180 ml of dry tetrahydrofuran was dropwise added thereto. The reaction mixture was stirred at -78° C. for 1.5 hours, and then 5 ml of a saturated ammonium chloride aqueous solution was added to terminate the reaction. The organic layer was extracted with diethyl ether, and the ether extract was washed with a saturated sodium chloride aqueous solution and dried over anhydrous magnesium sulfate. The solvent was distilled off under reduced pressure, and the residue was subjected to liquid separation between hexane and acetonitrile. The acetonitrile layer was subjected to distillation under reduced pressure to remove the solvent and to obtain the desired product as slightly yellow powder. Melting point: 108°-118° C. 
     Compounds IX-11 to IX-17 were prepared in the same manner as in Example 3-l.

     Compounds I-1-7 was prepared by the process of the following Example 4 (4-g). 
     EXAMPLE 4-g 
     Ethyl (E)-3,5-dihydroxy-7-[4&#39;-(4&#39;&#39;-bromophenyl)-6&#39;-methyl-2 &#39;-phenylpyrimidin-5&#39;-yl]hept-6-enoate (compound I-1-7) 
     500 mg (1×10 -3  mol) of compound II-7 was dissolved in 25 ml of dry ethyl ether and 3 ml of dry benzene, and the solution was cooled to -70° C. Then, 33 ml (about 5×10 -3  mol) of an about 0.15 mol/liter zinc borohydride-ethyl ether solution was added thereto, and the mixture was stirred under a nitrogen stream for 4 hours. After confirming the disappearance of the starting material II-7 by thin layer chromatography, 6 ml of methanol and then 12 ml of water were added at -70° C. to terminate the reaction. Then, 120 ml of water and 120 ml of ethyl ether were further added, and the mixture was adjusted to pH4 with a dilute acetic acid aqueous solution. The ether layer was washed with water and then with a saturated sodium chloride aqueous solution and dried over anhydrous magnesium sulfate. Then, the solvent was distilled off by an evaporator, and the residual solid was purified by silica gel column chromatography (eluent: benzene/ethyl acetate) to obtain the desired compound as slightly yellow powder. Melting point: 125.5°-127.5° C.

     213 mg (4.44×10 -4  mol) of compound I-1-8 was dissolved in 10 ml of ethanol. Then, 0.84 ml of a 0.5N sodium hydroxide aqueous solution was dropwise added thereto. The mixture was stirred at room temperature for further 2 hours. Then, ethanol was distilled off at 45° C. under reduced pressure, and 5 ml of distilled water was added thereto. The remaining starting material was extracted with ethyl ether. The aqueous phase was adjusted to pH2 by an addition of 0.1 ml of 2N hydrochloric acid. The reaction solution was extracted with ethyl ether, and the extract was washed with a saturated sodium chloride aqueous solution and dried over anhydrous magnesium sulfate. Then, the solvent was distilled off to obtain 190 mg (95.1%) of the desired product as colorless powder. Melting point: 52°-58° C.

     190 mg 4.22×10 -4  mol) of compound I-2-8 was dissolved in 2 ml of dry methylene chloride dehydrated by molecular sieve. Then, 220 mg (5.19×10 -4  mol) of N-cyclohexyl-N&#39;-[2-(methylmorpholinium)ethyl]carbodiimide p-toluene sulfonate (lactone-forming agent) was added thereto, and the mixture was stirred at room temperature for 5 hours. Then, 200 mg of the lactone-forming agent was further added, and the mixture was stirred at room temperature overnight. The reaction solution was washed with water and then with a saturated sodium chloride aqueous solution and dried over anhydrous magnesium sulfate. Then, the solvent was distilled off under reduced pressure, and the residue was purified by silica gel chromatography (eluent: 10% ethyl acetate/benzene) to obtain 120 mg (yield: 65.8%) of the desired product as colorless powder. Melting point: 177°-180° C. This compound was a mixture of two types of lactones (trans, cis) attributable to the two diastereomers (a mixture of erythro and threo) of I-2-8 used as the starting material. However, from the result of the thin layer chromatography analysis (silica gel; developing solvent: methyl-t-butyl ether/n-hexane/acetone=7/2/1 (v/v)) and of the NMR analysis, this product was substantially pure trans-lactone.

     100 mg (2.09×10 -4  mol) of compound I-1-8 was dissolved in 5 ml of dry toluene dehydrated by molecular sieve. Then, 360 mg of activated manganese dioxide was added thereto, and the mixture was stirred at room temperature for 3 days. 10 ml of benzene was added to the reaction solution, and manganese dioxide was removed by filtration with celite. A filtrate was decolored with activated charcoal, and then the solvent was distilled off. The residual oil was purified by silica gel column chromatography (eluent: benzene/ethyl acetate) to obtain 65 mg (65.3%) of the desired product as slightly yellow powder. Melting point: 47°-51° C.
